Multiple database value vs response comparison

We want to match multiple database value with multiple response value for the same field.
Ex -
Database value:
Alternate policy number:
AXTY003245
FRTO984352

Response value:
a:altpolnbr
FRTO984352
AXTY003245

Please let us know how can I match these values?
We are trying to put the assertion over here using groovy script so as to match these values between DB value and response value?
